CURTAIN-POLE ANGLE-PIECE.

SPECIFICATION forming part of Letters Patent No. 274,572, dated March 27, 1883.

Application filed March 7, 1882. (X model.)

To all whom it may concern Be it known that I, CHARLES DE QUILL- FELDT, of the city, county, and State of New York, have invented certain new and useful Improvements in (Jurtain'Pole Angle-Pieces, of which the following is a specification.

This invention relates to an improved angle-piece for curtain-poles for bay-windows and similar purposes, whereby the different pole-sections are so connected that on being adjusted they swing in the longitudinal center plane of the angle-piece, and which is constructed in such a manner that the curtainrings can pass freely over the joint, and that a neat and regular connection of the pole-sections is obtained.

The invention consists of an angle-piece for curtain-poles, which is made of truncated cylindrical end portions, which are attached to the pole-sections by suitable cap-pieces and fastening-screws, and of a spherical connecting-joint, the parts of which are coupled together in such a manner that the pole-sections are adjusted toward each other to any desired angle in a plane passing longitudinally through the center plane of the anglepiece.

In the accompanying drawings, Figure 1 represents a plan of three pole-sections connected by my improved angle-pieces. Fig. 2 is a verticallongitudinal section of the an glepiece, showing the parts forming the joint detached from each other. Figs. 3 and 4 are top views of the angle-piece in different positions. Fig. 5 is a side view, and Fig. 6 avertical longitudinal section, of the same. Figs. 7

and 8 are a longitudinal and a vertical longitudinal section of a modified construction.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A A represent the curtain-pole sections, which are jointed by means of truncated cylindrical portions (land end caps, 0, having fixed fastening-screws D, tothe ends of the pole-sections A A. Each cylindricalport-ion G is provided with ahemispherical portion, a, the two hemispheres of the adjoining cylinders G G hein g jointed by means of an interior circular band, b, which projects 5 above the edge of the hemisphere and forms a shoulder or guide for the connecting hemisphere, as shown in Figs. 2 and 6. In this case both hemispheres (t aof the joint are first put together, then soldered or otherwise fast ened to their cylindrical portions, after having been. placed in position inside of the same, whereby the angle-piece is completed. Instead of using two hemispherical portions, a loose,

' spherical portion, a, may be employed, which is 6 5 connected by fixed interior arms, d, of the cylindrical portion 0, said arms passing through slots into the sphere, where they are connected by a pivot-pin, d. The pivot-pin d passes through eyes of the arms and vertio cally through the center of the sphere, as shown in Figs. 7 and S. in place of the interior arms, an exterior band which encircles I the sphere, and which is set into a groove of the same, may he used, said band being attaehed to one of the cylindrical portions 0, while the sphere is attached to the other cylindrical portion 0. In all these cases ajoint is obtained in which the pole sections must move in a plane which is the horizontal cen- Sc ter plane of the angle-piece of the joint. The end caps, G, are attached to the cylindrical portions 0 0, either rigidly or so as to turn thereon, in which latter arrangement the poles may be turned around their axes for proper 8 adjustment. The inner sides of the cylindrical portions G G of the angle-pieces are an ranged at such an angle of inclination to the outer sides that the former inelose an oblique angle with each other when the cylindrical portions are placed in line with pole-sections, as shown in, Fig. 3, which angle is again produced when the pole-sections are placed at right angles to each other, as shown in Fig. 4. When the angle-pieces are applied to the pole-sections a reliable connection is obtained, in which the poles are moved for adjustment in the horizontal center plane of the anglepiece, which forms the distinguishing feature of this invention. V

As the angular piece has no enlarged or projecting parts, the curtain-rings can he slipped readily over it, while, owing to the arrangement of the connecting mechanism at the in terior of the spherical joint, the angle-piece axially-turning caps applied to the outer end presents a neat and symmetrical appearance.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- 1. In an angle-piece for curtain-poles, the combination of truncated cylindrical portions, having end caps and fastening devices, with a spherical connecting-joint, whereby the poles may be adjusted to any angle in the horizontal plane of the longitudinal axes of the poles, substantially as specified.

2. In an angle-piece for curtain-poles, the combination of truncated cylindrical portions,

of'the cylindrical portions, fastening devices I 5 for attaching the caps to the pole ends, and a spherical joint, whereby the inner ends of the cylindrical portions are connected, substantially as described. f

- In testimony that I claim the foregoing as 20 my invention I have signed my name in presence of two subscribing witnesses.
